This neighborhood cafe offers reliable, authentic Thai food in a setting that could exist only at this particular bend in Royal Street. In a sweetly decorated space between the R Bar and La Peniche, SukhoThai serves mussels steamed over kaffir lime leaves and crushed lemongrass, whole fried Gulf fish in a fierce chile sauce and a pad Thai that should satisfy your craving. The BYO liquor policy helps keep the tab low.
